ABB Bailey NKAS01-10 Termination Cable

This analog module termination cable connects ABB Bailey INFI 90 analog modules to field termination assemblies. It carries analog signals between the I/O module and the field wiring terminals. Therefore, it simplifies installation and maintenance of analog control systems.

Physical and Cable Specifications

The ABB Bailey NKAS01-10 measures 10.0 meters in total assembled length. Moreover, its cable weight equals approximately 0.85 kg for flexible routing within cabinets. Two 48-pin male connectors terminate each end of this termination cable. Additionally, the cable contains 48 individually shielded conductors for signal integrity.

Cable Construction and Signal Isolation

The ABB Bailey NKAS01-10 uses 48 individually shielded conductors for robust signal transmission. Specifically, foil shielding on each wire prevents crosstalk between adjacent analog signals. In addition, an overall braided shield provides additional protection against external electromagnetic interference. Moreover, the 100 ohm impedance maintains signal integrity for differential analog pairs. Furthermore, the gold-plated connector pins ensure reliable electrical contact over many insertions. Consequently, this cable maintains analog signal accuracy even in electrically noisy turbine environments.

Physical Layout and Termination

You will find screw-lock connectors at both ends of this termination cable. For instance, one end connects to the analog I/O module in the INFI 90 rack. In addition, the other end connects to the field termination assembly (FTA) near field wiring. Moreover, the 10 meter length allows flexible placement of termination assemblies. Furthermore, the cable remains flexible enough for routing through cable trays or conduits. Thus, you can separate field wiring from the control rack to reduce electrical noise.

Installation and Routing Guidelines

This termination cable requires a minimum bend radius of 7.5 cm for safe installation. For instance, avoid sharp bends or kinking the cable during rack routing. In addition, secure the cable using plastic ties at regular intervals for strain relief. Moreover, do not run the cable parallel to high-voltage power lines. Furthermore, the gray PVC jacket resists oil, moisture, and industrial chemicals. Therefore, the ABB Bailey NKAS01-10 suits harsh turbine control room environments.
